Derived from crop based oil, InterLock® adjuvant considerably reduces the amount of fine particles in the spray pattern without thickening the spray. Field studies with water-sensitive paper showed the benefit of InterLock® adjuvant as well as Preference® adjuvant, a highly effective nonionic surfactant, which had more droplets throughout the canopy. By keeping more spray droplets within the most effective size range, InterLock® adjuvant helps improve coverage, increases canopy penetration, and reduces drift and evaporation of pesticides, whether they are applied by ground or air.
